Ashwagandha: Effects on Stress, Inflammation and Immune Cell Activation
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Due to the increased use of alternative medicine, supplements and herbs are consumed more frequently in the treatment of common ailments. This pilot study investigates the immune, anti-inflammatory and anti-stress effects of Ashwagandha in human subjects.
Liquid extract of the herb will be taken followed by milk; this mode of administration will be used as it approximates the traditional administration as well as making self administration easier for participants. Extract will be taken in 3 milliliter quantities 2 times per day, (morning and evening), for five days. Total dosage of 6 milliliters will approximate the higher end of the traditional daily dosage of 6 grams daily of powdered root.
Flow of visit:
25 participants will arrive at the research lab and after being consented, filling out health histories and two stress questionnaires, (POMS and STAI Self-Evaluation), average milk intake questionnaire. The 25 participants will receive blood draws. They will then be administered the herb extract, milk and instructions for taking them.
Subjects will return to the research institute after 24 hours for a second blood draw and then after 5 days for a final blood draw and two more stress questionnaires, (POMS and STAI Self-Evaluation).
Once the blood samples are drawn, they will be refrigerated and processed within 24 hours at the NCNM laboratory. Initially they will be centrifuged to separate the white from the red blood cells using Ficoll separating tubes. Then the white blood cells will be stained using CD69 marker (Cytokine Detection type 69) which assesses cell-surface phenotypic markers in combination with intracellular cytokines, measuring response to activation. It is especially effective for rare-event, antigen-specific events, such as the administration of a specific immune-stimulating herbal tincture. We will also stain with other similar florescent CD markers specific for CD4 T-cells, CD8 T-cells, B-cells, NK cells, and macrophages. These markers will be analyzed using a FACScan flow cytometer, which will count the number of cells that have been activated in each subtype of the immune cell and overall action. Blood will also be analyzed for cortisol levels and inflammatory cytokines, (IL-1, IL-6 and TNF-alpha) using the ELISA assay procedure.
